By means of the random phase approximation (RPA) calculation based on cranked deformed Woods-Saxon potential, we investigate how rotational motion affects the properties of octupole vibrations built on superdeformed states in 40 Ca. A major structure change of the superdeformed yrast states toward a reflection-asymmetric shape is suggested to take place in the region of angular momentum a little higher than the observed maximum value 16~, owing to a cooperative effect of octupole vibrational
